As the Universe ages, will it eventually fade away entirely? The earliest signal we’ve ever directly detected from the Universe comes to us from shortly after the Big Bang: when […]
The latest gravitational wave data from LIGO and Virgo finally shows us the truth: there are no “gaps” in the masses of black holes.
We still don’t know how the information encoded onto it gets out. No matter what you do in the Universe, its overall entropy always increases. Even when we put things in […]
As long as it remains operational, we’ll have a chance to conduct groundbreaking science with it. In the history of spaceflight, only five spacecraft ever launched by humanity possess enough energy […]
It doesn’t have to be a science-fiction dream. For as long as human beings have been watching the night sky, we’ve dreamed of visiting other worlds and truly seeing what’s […]
If we want our conclusions to be meaningful, our data had better be robust. When it comes to the Universe, there’s a whole lot that doesn’t add up. All the matter […]
Quantum physics just keeps getting weirder, even as it gets more fascinating. “Is it a wave or is it a particle?” Never has such a simple question had such a […]
Apple sold its first iPod in 2001, and six years later it introduced the iPhone, which ushered in a new era of personal technology.
CERN’s bold new proposal has physicists confronting the biggest question of all: is building a new collider worth it? If you want to discover anything novel about the natural, physical […]
An interview with filmmaker Jason Sussberg about his new film about Stewart Brand and the importance of culture in achieving progress.
Named M51-ULS-1b, it’s certainly a curious astronomical event. But the evidence is far too weak to conclude “planet.”
Anxiety can be good or bad. It turns out that it’s really up to you.
When we look out at the Universe, even with Hubble, we’re only seeing the closest, biggest, brightest galaxies. Here’s where the rest are.
Contrary to what some might think, the brain is a very plastic organ.
During World War II, Nazi engineers allegedly tried to create UFO-shaped military aircraft.
Device for harnessing terahertz radiation might enable self-powering implants, cellphones, other portable electronics.
The controversy over the universe’s expansion rate continues with a new, faster estimate.
A famous thought experiment from the 1970s is more relevant today than ever before.
Not nearly well enough. And we should all be concerned. In 1859, the science of solar physics truly began with the largest eruption in recorded history: the Carrington event. Prior […]
Just because you have “star” in your name doesn’t mean you are one. When we think about the objects in our Universe, they fall into two categories: self-luminous objects, like stars, […]
It wasn’t the birth of space and time. But it was truly essential to our cosmic story. For more than 50 years, we’ve had definitive scientific evidence that our Universe, as […]
One man studied apes for 50 years. He says nature isn’t as cruel as you think.
Researchers from Harvard receive permission for a test that may help cool Earth and fight global warming.
From exoplanets to supermassive black holes to the first stars and galaxies, Webb will show us the Universe as we’ve never seen it before.
The Standard Model and General Relativity can’t be all there is. But how will we discover what lies beyond them? One of the biggest problems with physics is that, apart from […]
A colliding star may have triggered the drastic transformation.
Some scientists believe the lightning-produced frequencies may be connected to our brain waves, meditation, and hypnosis.
Researchers create a device to test a 50-year-old physics theory from the famed Roger Penrose.
Now that it’s fully commissioned, the James Webb Space Telescope begins its exploration of the Universe. Here are its first science images!
